The centralized control hydraulic hoist has the advantages of convenient use and maintenance, convenient production and manufacture, easy assembly, and high degrees of automation and reliability.
Description
Technical field
The present invention relates to a kind of gate hoist, particularly a kind of centralized control hydraulic water conservancy gate hoist.
Background technique
At present, the water conservancy gate opening/closing of extensive use equipment has substantially all adopted the hydraulic type transmission.But the hoist of most utilizations is oil hydraulic pump standing posture or integrated form hoist now.Oil hydraulic pump standing posture hoist adopts the mode of solenoid valve commutation to drive the hoist oil cylinder, drive the unlatching of gate, exist operation, maintenance workload to weigh, volume, installing space are excessive, on-the-spot pipeline complicated layout, the shortcoming that cost is high is though and the integrated form hoist has solved this problem, the valve group employing cartridge valve group of integrated hydraulic hoists.Steel ball and spring formula cartridge valve group pressure can't guarantee that it is unreliable to work, cone valve type cartridge valve group processing request and the high and leakage easily to the equipment requirement, trouble shooting and maintenance difficult.
